Kleeman makes one, Renntech makes one, VRTuned makes one, Malone tunes them, Diablosport has a unit out for the V6, Green Diesel Engineering has one, lots of options.

SL320 is talking about Rocketdog, I don't know if they do the OM642 or not.

Different engine, but I am running stock "tune" but an EGR delete on my OM648 E320 CDI and noticed a little more fuel economy, less smoke, and a little faster spool with just that.
